The most important skill of great players is between the ears. That's why Doncic is so undervalued in this draft. Plenty of guys jump higher, are longer, shoot better, etc. But on good teams, basketball is a 5 on 5 game, and if there is a player in this draft with a better understanding of basketball, I haven't seen him.
So the rumors that Ainge is targeting Doncic may be a smokescreen, but I hope they are not. I'd rather give assets for a cost controlled young player like Doncic that for a rental of Leonard.
The other two guys I think are undervalued in this draft are Bamba and my favorite Latvian, Rodions Kurucks. People focus on Bamba shooting uncontested threes in a gym, but he looks well coached and fundamentally sound to me. He's a great target for the lob on the pick and roll. As for Kuruks, he's a better player than Musa (although Kuruks is a year older). They're both too skinny, but Kuruks is better defensively. The difference is, Musa played in the Croatian league and got plenty of playing time. Kuruks was with FCB Barcelona and got almost no playing time because he refused to sign an extension. Kuruks would be high on my list if I had a pick in the 35-45 range.
